I assume booting verbose doesn't provide any more clues? I've sometimes gotten an extra clue from a hang during boot by building with option BUS_DEBUG. Even if you don't suspect the newbus routines as directly being the problem, sometimes you get a bit more info about what was happening at the time of lockup. -- Ian _______________________________________________ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"
